1. General Introduction to Hydrogenated Castor Oil
Hydrogenated Castor Oil (also known as Castor Wax) is a premium product harvested and undergoing a controlled hydrogenation process from the seed oil of the castor plant. Researched and manufactured on modern production lines by Jiangxi Alpha Hi-Tech Pharmaceutical Co., Ltd (China),this is a top-tier excipient that fully meets the most stringent technical standards in the global pharmaceutical and healthcare manufacturing industries.
Hydrogenated Castor Oil plays a core role as an excellent glidant, lubricantand anti-adherent for tablets. At the same time, it serves as an ideal release-modifying agent to form a lipid matrix system in sustained-release tablet formulations. Furthermore, thanks to its characteristic waxy structure and high melting point, the product acts as a perfect consistency-modifying, thickening, and suspending agent forsoft gel capsule fills, as well as premium topical ointments andcreams.
2. Active Ingredient Profile of Hydrogenated Castor Oil
Main Composition: A mixture of fatty acid triglycerides, primarily 12-hydroxystearic acid formed by complete hydrogenation.
Physical Form: Fine powder or hard waxy flakes, white to slightly yellowish-white.
Key Properties: Excellent glidant and lubricating properties, high melting point, chemically inert, and free of metal ion radicals.
Solubility: Practically insoluble in water and 96% ethanol; soluble in chloroform, ether, and other organic solvents upon heating.
Quality Standards: Complies with international pharmacopoeia standards: USP/NF, EP, BP, ChP.
Standard Control Parameters:
Identification and fatty acid composition (especially 12-hydroxystearic acid content).
High and stable melting range.
Iodine value (controlled at a very low level to ensure complete hydrogenation), acid value, and hydroxyl value.
Limits for heavy metals, nickel (residual catalyst), and sulfated ash.
Microbial limits tailored for pharmaceutical manufacturing applications.
3. Key Advantages Hydrogenated Castor Oil
High chemical stability: The hydrogenation process provides the material with exceptional antioxidant capabilities, preventing rancidity or degradation and significantly extending the shelf life of the finished product.
High performance multi functional excipient: Demonstrates outstanding efficacy in core roles, including tablet lubricant, anti-adherent, dispersion thickener, and release-controlling matrix former.
Excellent heat resistance and gloss enhancement:Its high melting point helps maintain a solid structure, making it highly suitable for heat-sensitive active ingredients.
Ideal safety and compatibility profile: Highly compatible with most active pharmaceutical ingredients (APIs), chemically inert, and metal-radical-free, minimizing potential chemical interactions and incompatibilities during formulation.
Enhanced formula bioavailability: Supports and optimizes bioavailability for microemulsions, solid dispersions, and nano-drug formulations.
Compliance with strict international standards:Manufactured in an EXCIPACT GMP-certified facility for pharmaceuticals, with stock readily available in GSP/GDP warehouses to ensure seamless production timelines and optimal manufacturing costs.
4. Applications of Hydrogenated Castor Oil
In Pharmaceuticals
Tablets and hard capsules: Functions as a high-efficiency lubricant and anti-adherent at low concentrations, seamlessly supporting tableting processes (direct compression and wet granulation).
Sustained- release dosage forms: Acts as a lipid matrix system, enabling precise control over the diffusion rate and ensuring a stable, prolonged release of the drug substance.
Soft gel fills and dispersions: Utilized as a consistency-modifying, thickening, and suspending agent for soft gelatin capsule fills.
Ointments, creams and suppositories:Functions as a stiffening and thickening agent to adjust viscosity, enhance hardness, improve bioadhesion, and stabilize the physical structure of topical formulations.
In Cosmetics and Personal Care
Lipsticks and sticks form products: Enhances mechanical hardness, provides a natural gloss, and prevents breaking, melting, or "sweating" caused by environmental temperatures.
Creams and emulsions:Stabilizes emulsion systems, delivers a rich and smooth product texture, improves skin retention and absorption, and enhances moisture retention on the skin surface.
